METHOD OF TRANSFERRING IMPRESSIONS OF LINES OR CHARACTERS Filed June 1,1954 INVENTOR. M W MM FIG. 3 y

United METHQD F TRANSFERREWG IMPRESSIONS OF LINES OR CHARACTERS Thisinvention relates to a method of transferring duplications ofimpressions of lines or characters from one surface to another surface.

In the art as it now exists, duplications of lines or characters onanother surface or object is accomplished by transferring impressions ofthe lines or characters through the medium of a transfer sheet coatedwith a transferring element in direct contact with the surface uponwhich it is desired to transfer duplications of the lines or characters,at the time the lines or characters are originaly inscribed upon theopposite surface of the transfer sheet.

This method of transferring impressions of lines or characters islimited in its application, to such extent, that the actual transferringelement must always be in direct contact with the object, upon which thelines or characters are to be duplicated, at the time such lines orcharacters are originally impressed upon the opposite side of the sheet.

It is the object of my invention to overcome these limitations andobjections by providing a method of transferring duplications ofimpressions of lines or characters, that will permit the transferring ofduplications of lines or characters from one surface to another by theapplication of pressure upon the transfer sheet over the lines orcharacters.

It is an object of my invention to provide for transferring duplicationsof impressions of lines or characters, which may be designated as atwo-ply laminated structure, consisting of an arrangement of parts in amanner that a duplicating substance can be transferred to a transfersheet for subsequently transferring impressions of lines or charactersto a surface distinct from the transfer sheet.

It is a further object of my invention to provide for transferringimpressions of lines or characters to curved, planar or uneven surfaces.

It is also an object of my invention to provide for transferringimpressions of lines or characters, which lines or characters werecaused to be formed upon the reverse surface of a transfer sheet by aninstrument, such as a pen, pencil, stylus or typewriter key, or othersuitable instrument, by applying direct pressure by means of suchinstrument against its front surface.

It is the further object of my invention to provide for transferringduplications of impressions of lines or characters, formed by a backingup sheet coated With a duplicating substance of such body andconsistency that lines or characters inscribed on the front side of thetransfer sheet will cause the rear surface to pick up a sufficientquantity of the duplicating substance to allow impressions of the linesor characters to be duplicated upon another surface when impressed uponit and pres sure is applied to the front surface of the transfer sheetover the lines or characters.

In the following description I will describe a preferred application ofmy invention. It is to be understood, however, that my invention can bepracticed and used tates atent O 2,708,647 Patented May 17, 1955 2 withmultiples of one of the structures herein set forth.

In the accompanying drawings- Figure l is a plan view of sheet 1 and 4of a structure by which my invention may be practiced with sheet 1turned back.

Figure 2 is a partial section of an embossed character.

Figure 3 is a view illustrating the application of sheet 1 on a surface.

Figure 4 is a section on line 22 of Figure 2.

Figure 5 is a view showing the arrangement of the ribbon runners.

Referring to the drawings, I provide a thin flat impressible transfersheet 1 composed of flexible material, comprising sides 2 and 3. To thereverse side 3 of sheet 1, I attach a removable two-sided backing sheet4 of substantially equal area, partially coated with an adher- 7 ingduplicating substance 5. Using a tacky adhesive substance 6 common toboth surfaces located on the outer margins, I hold said duplicatingsubstance 5 in contact with side 3 of sheet 1. By using a suitableinstrument I inscribe lines or characters upon side 2 of sheet '1applying sufiicient pressure to cause pressure as indicated at '7 on thesurface of sheet 1 resulting in duplication S of said lines orcharacters on side 3. The pressure I apply in forming said lines orcharacters causing said duplicating substance 5 to adhere to said linesor characters S in such amount and consistency to allow said duplicatingsubstance 5 to be transferred to a subsequent surface 9 when saidbacking sheet 4 is removed from contact with sheet 1. I then remove saidbacking sheet 4 from contact with said lines or characters 8 on sheet 1,bringing said transfer sheet 1 to bear upon a surface 9 upon which Idesire to transfer impressions of said lines or characters 3, I thenapply direct pressure to side 2 on said transfer sheet 1 over said linesor characters 8, transferring exact duplications 10 of said lines orcharacters 8 to said surrace 9. For preservation of the texture of thematerial forming said duplicated lines or characters I leave sheet 1 inplace over said lines or characters 10 after transferring saidimpressions. To facilitate separating and handling sheet 1 and 4, Iinsert uncoated continuous flat ribbon runners 11, backed up in contactalong an edge, including extensions 12 and 13 located on both sides ofsheet 1 and 4.

The invention is not limited to the material of sheet one. If theincribing is by way of pen, pencil or typewriter ribbon, the sheet maybe opaque. However, film may be employed such as cellulose film,regeneraled cellulose, glassine or cellophane may be employed,particularly where a stylus or noninked type is employed.

Having thus described my invention, What I claim as new and desire tosecure by Letters Patent is:

l. The method of marking a surface with characters which includes thestep of inscribing with the application of pressure such characters onthe front face of a transfer sheet, simultaneously producing an image ofsuch characters on the rear face of such sheet by the same applicationof pressure accompanying such inscribing, said image being in pressuretransferable material, applying said sheet to said surface with saidrear face in contact with said surface and thereafter applying pressureto the front face thereof for transferring said image to said surface.

2. The method of marking shipping instructions on the surface of apackage which includes the step of inscribing with the application ofpressure such instructions on the front face of a transfer sheet,simultaneously producing an image of such instructions on the rear faceof such sheet by the same application of pressure accompanying suchinscribing, said image being in pressure transferable material, applyingsaid sheet to the said surface with said rear face in contact with saidsurface and thereafter applying pressure to the front face thereof fortransferring said image to said surface.

3. The method of marking a surface with characters which includes thestep of inscribing with the application of pressure such characters onthe front face of a transfer sheet of film material, simultaneouslyproducing an image of such characters on the rear face of such sheet bythe same application of pressure accompanying such inscribing, saidimage being in pressure transferable material, applying said sheet tosaid surface with said rear face in contact with said surface andthereafter applying pressure to the front face thereof for transferringsaid image to said surface.

4. The method of marking shipping instructions on the surface of apackage which includes the step of inscribing with the application ofpressure such instructions on the front face of a transfer sheet of filmmaterial, simultaneously producing an image of such instructions on therear face of such sheet by the same application of pressure accompanyingsuch inscribing, said image being in pressure transferable material,applying said sheet to the said surface with said rear face in contactwith said surface and thereafter applying pressure to the front facethereof for transferring said image to said surface.

5. The method of marking a surface with characters which includes thestep of arranging a sheet bearing pressure transferabie material on oneface thereof with such face in contact with the rear face of a transfersheet, inscribing by the application of pressure, characters on thefront face of said transfer sheet and thereby simultaneously producingan image of such characters in the transferable material of the firstmentioned sheet on the rear face of the transfer sheet, removing saidfirst mentioned sheet from said transfer sheet, applying said transfersheet to said surface with said rear face in contact with said surfaceand thereafter applying pressure to the front face of said transfersheet for transferring said image to said surface.
